Fedora 44 libsoup3 Important Credential Leakage Patch CVE-2026-1539

March 30, 2026
Add patch for CVE-2026-1539 (Also remove Proxy-Authorization header on cross origin redirect)
Summary
Libsoup is an HTTP library implementation in C. It was originally part
of a SOAP (Simple Object Access Protocol) implementation called Soup, but
the SOAP and non-SOAP parts have now been split into separate packages.
libsoup uses the Glib main loop and is designed to work well with GTK
applications. This enables GNOME applications to access HTTP servers
on the network in a completely asynchronous fashion, very similar to
the Gtk+ programming model (a synchronous operation mode is also
supported for those who want it), but the SOAP parts were removed
long ago.
